Notes to Financial Statements
Substantial Doubt about Going Concern [Text Block]	2. Going Concern The Company has incurred historical losses from operations and expects to continue to incur operating losses in the near future. The Company will need to raise additional capital to grow its business, fund operating expenses and make interest payments. The Company’s ability to fund its liquidity needs is subject to various risks, many of which are beyond its control. The Company will seek additional funding through debt borrowings, sales of debt or equity securities or strategic partnerships. The Company cannot guarantee that such funding will be available on a timely basis, in needed quantities or on terms favorable to the Company, if at all. These factors and other indicators raise substantial doubt about the Company’s ability to continue as a going concern within one year from the filing date of this report. The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result should the Company be unable to continue as a going concern.

Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	3. Summary of Significant Accounting Polices There have been no material changes in the Company’s significant accounting policies to those disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such Securities and Exchange Commission (“SEC”) rules and regulations and accounting principles applicable for interim periods. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Events subsequent to the balance sheet date have been evaluated for inclusion in the accompanying condensed consolidated financial statements through the date of issuance. Operating results for the three months ended March 31, 2024 are not necessarily indicative of the results that may be expected for the Company’s fiscal year ending December 31, 2024. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in ThermoGenesis Holdings’ Annual Report on Form 10-K for the year ended December 31, 2023. Principles of Consolidation The consolidated financial statements include the accounts of ThermoGenesis Holdings and its wholly-owned subsidiaries, ThermoGenesis Corp. and TotipotentRX Cell Therapy, Pvt. Ltd and ThermoGenesis Corp’s majority-owned subsidiary, CARTXpress Bio, Inc. (“CARTXpress Bio”). All significant intercompany accounts and transactions have been eliminated upon consolidation. The 20% ownership interest of CARTXpress Bio that is not owned by ThermoGenesis Holdings is accounted for as a non-controlling interest as the Company has an 80% ownership interest in CARTXpress Bio. Earnings or losses attributable to other stockholders of a consolidated affiliated company are classified separately as "non-controlling interest" in the Company's consolidated statements of operations. Net loss attributable to non-controlling interests reflects only its share of the after-tax earnings or losses of an affiliated company. The Company's condensed consolidated balance sheets reflect non-controlling interests within the equity section. Recently Issued Accounting Standards In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which is intended to enhance the transparency and decision usefulness of income tax disclosures. Notably, the ASU requires entities to disclose specific categories in the effective tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold, as well as disclosures of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024 on a prospective basis. Retrospective application to each period presented in the financial statements is permitted. We are currently evaluating the impact of this standard on our consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” which requires all public entities, including those that have a single reportable segment, to provide enhanced disclosures primarily about significant segment expenses. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The new guidance is required to be applied on a retrospective basis, with all required disclosures to be made for all prior periods presented in the financial statements. The segment expense categories and amounts disclosed in prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. We are currently evaluating the impact of this standard on our consolidated financial statements. In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements—Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative.” This ASU modifies the disclosure or presentation requirements of a variety of Topics in the Codification by aligning them with the SEC’s regulations. The amendments to the various Topics should be applied prospectively, and the effective date for the Company for each amendment will be determined based on the effective date of the SEC’s removal of the related disclosure from Regulation S-X or Regulation S-K. If the SEC has not removed the applicable requirement by June 30, 2027, then the related amendment in ASU 2023-06 will be removed from the Codification and will not become effective. Early adoption of this ASU is prohibited. We are currently evaluating the new ASU to determine if it will have an impact on the disclosures or presentation in our consolidated financial statements.

Related Party Transactions Disclosure [Text Block]	4. Related Party Transactions Convertible Promissory Note and Revolving Credit Agreement In March 2017, ThermoGenesis Holdings entered into a Credit Agreement with Boyalife Group (USA), Inc. (the “Lender”), which is owned and controlled by the Company’s Chief Executive Officer and Chairman of our Board of Directors. The Credit Agreement, as amended, grants the Company the right to borrow up to $10,000,000 (the “Loan”) at any time prior to the maturity date. On January 5, 2024, the Company entered into Amendment No. 3 (the "Note Amendment”) to its Second Amended and Restated Convertible Promissory Note with Boyalife Group Inc. (the "Note”), and Amendment No. 4 (the "Credit Agreement Amendment”) to its First Amended and Restated Revolving Credit Agreement with Boyalife Group Inc. (the "Credit Agreement”). The Note Amendment extended the maturity date of the Note from December 31, 2023 to December 31, 2024 (the “Maturity Date”), and provided that beginning January 1, 2024, accrued and unpaid interest of approximately $634,000 was due and payable on or before July 1 and December 31 of each year. Accrued and unpaid interest as of December 31, 2023, (the "December 2023 Capitalized Amount”) is to be paid in equal monthly installments of approximately $106,000 over the first six months of 2024. Any unpaid portion of the December 2023 Capitalized Amount shall bear interest at an annual rate of twenty-two percent (22%), and accrued and unpaid interest on the December 2023 Capitalized Amount shall be due and payable on July 1, 2024. The Credit Agreement Amendment updated the defined term "Termination Date” in the Credit Agreement to December 31, 2024. The Company performed a debt extinguishment vs. modification analysis on the Note Amendment and determined that it would be considered an extinguishment, due to an increase of more than 10% to the value of the embedded conversion option. However, no gain or loss was recorded in the condensed consolidated statements of operations for the quarter ended March 31, 2024 as it was determined that the fair value of the Note Amendment and accrued interest was $7,912,000 both before and after the extension. On March 15, 2024, the Company received a conversion notice from the Lender to convert $1,278,000 of the outstanding principal and $285,000 of the 2024 outstanding accrued interest for a total of $1,563,000. As of March 31, 2024, the outstanding principal and accrued interest of the Note was approximately $6,424,000. The Credit Agreement Amendment and the Note Amendment, provide that the principal and all accrued and unpaid interest under the Loan will be due and payable on the Maturity Date of December 31, 2024. The Loan bears interest at 22% per annum, simple interest. The Company has five business days after the Lender demands payment to pay the interest due before the Loan is considered in default. The Loan can be prepaid in whole or in part by the Company at any time without penalty. The following summarizes the Note: Maturity Date Stated Interest Rate Conversion Price Face Value Debt Discount Carrying Value March 31, 2024 12/31/24 22 % $ 0.38 $ 6,000,000 $ (1,794,000 ) $ 4,206,000 December 31, 2023 12/31/23 22 % $ 0.79 $ 7,278,000 $ - $ 7,278,000 The Note includes a down-round anti-dilution provision that lowers its conversion price if the Company sells shares of common stock or issues convertible debt at a lower price per share. In 2024, the down-round provision was triggered, as noted below: For the three months ended March 31, 2024, when the conversion price of the Note was $0.79 per share, under an At The Market Offering Agreement with H.C. Wainwright & Co., LLC (“Wainwright”), pursuant to which the Company can offer and sell, from time to time, shares of its common stock, $0.001 par value, the Company sold shares of its common stock through multiple transactions with an average selling price of $0.45, resulting in a triggering event lowering the conversion price of the Note to $0.38. The triggering event created an incremental value of approximately $2,789,000 which was treated as a discount to the carrying amount of the Note and will be amortized over its remaining term. A Black-Scholes pricing model was utilized to determine the change in the before and after incremental value of the conversion option at each triggering event, with the following inputs: January 2024 Conversion price before $ 0.79 Conversion price after $ 0.38 Term (years) 0.94 Volatility 122.7 % Dividend rate 0 % Risk free rate 4.38 % The Company amortized $995,000 and $3,604,000 of debt discount related to triggering events for the Note to interest expense for the three months ended March 31, 2024 and 2023, respectively. In addition to the amortization, the Company also recorded interest expense related to the Note of $392,000 and $389,000 for the three months ended March 31, 2024 and 2023 respectively. The interest payable balance for the Note was $424,000 and $634,000 as of March 31, 2024 and December 31, 2023, respectively.

Debt Disclosure [Text Block]	6. Convertible Promissory Note July 2019 Note On July 23, 2019, the Company entered into a private placement with Orbrex (USA) Co. Limited (“Orbrex”), pursuant to which the Company issued and sold to Orbrex an unsecured convertible promissory note in the original principal amount of $1,000,000 (the “July 2019 Note”). The July 2019 Note, as amended, bared an interest rate of twenty-four percent (24%) per annum which was payable quarterly in arrears. On January 31, 2023, the Company entered into Amendment No. 3 to the July 2019 Note which extended the maturity date from January 31, 2023 to July 31, 2023 and changed the fixed conversion price to $2.87 per share. On the July 2023 maturity date, the Company entered into an Amendment No. 4 to the July 2019 Note, which extended the maturity date of the July 2019 Note to January 31, 2024 and changed the fixed conversion price to $1.07 per share. The Company performed a debt extinguishment vs. modification analysis on the Amendment No. 3 to the July 2019 Note and determined that the extension would be considered an extinguishment, due to an increase of more than 10% to the value of the embedded conversion option. The Company determined that the fair value of the July 2019 Note after the amendment was $1,239,000 representing a $239,000 increase in its fair value. The increase will be recorded as a premium to the July 2019 Note and amortized over the remaining term. During the three months ended March 31, 2023, the holder of the July 2019 Note converted $603,000 of the Note for 215,000 shares. The July 2019 Note matured on January 31, 2024, at which time the Company paid the outstanding balance of $398,000. The following summarizes the July 2019 Note: Maturity Date Stated Interest Rate Conversion Price Face Value Debt Discount Carrying Value December 31, 2023 1/31/24 24 % $ 0.79 $ 397,000 $ (19,000 ) $ 378,000 The Note includes a down-round anti-dilution provision that lowers its conversion price if the Company sells shares of common stock or issues convertible debt at a lower price per share. In 2024, the anti-dilution provision was triggered, as noted below: In January 2024, through multiple transactions under the At The Market Agreement with Wainwright, the Company sold shares of its common stock with an average selling price of $0.45, resulting in a triggering event lowering the conversion price of the Note to $0.38. The triggering event created an incremental value of approximately $37,000 which was treated as a discount to the carrying amount of the Note and will be amortized over its remaining term. A Black-Scholes pricing model was utilized to determine the change in the before and after incremental value of the conversion option at each triggering event, with the following inputs: January 2024 Conversion price before $ 0.79 Conversion price after $ 0.38 Term (years) 0.02 Volatility 83.9 % Dividend rate 0 % Risk free rate 4.38 % The Company recorded amortization expense related to triggering events for the July 2019 Note of $72,000 and $41,000 for the three months ended March 31, 2024 and 2023, respectively. Additionally, an amortization expense of $15,000 and $174,000 related to a debt premium for the July 2019 Note was recorded for the three months ended March 31, 2024 and 2023. Interest expense related to the July 2019 Note was $8,000 and $42,000 for the three months ended March 31, 2024 and 2023. When the July 2019 Note matured on January 31, 2024, the Company paid approximately $102,000 for the accrued interest payable.

Share-Based Payment Arrangement [Text Block]	7. Stockholders Equity Common Stock On March 15, 2023, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with an accredited investor (the “Investor”) pursuant to which the Company agreed to issue and sell to the Investor in a private placement (the “Offering”) (i) 125,000 shares of its common stock, $0.001 par value (the “Common Shares”), (ii) 946,429 pre-funded warrants to purchase Common Shares at a purchase price of $2.80, and (iii) warrants to purchase up to an aggregate 1,071,429 Common Shares were issued (the “Underlying Shares”). The warrants have an exercise price of $2.65 per share and are exercisable immediately upon issuance and expire five In connection with the Offering, the Company entered into a Warrant Amendment Agreement (the "Warrant Amendment Agreement”), dated March 15, 2023, with the Investor, whereby the Company agreed to amend existing warrants, held by the Investor, to purchase up to an aggregate of 158,731 shares of common stock under the Warrant Amendment Agreement that were previously issued in October 2022. These warrants had an exercise price of $6.30 per share and pursuant to the Warrant Amendment Agreement, have been amended to reduce the exercise price to $2.65 per share effective upon the closing of the Offering. During the quarter ended March 31, 2023, 158,731 common warrants were exercised. The Company received approximately $421,000 from the exercises of the warrants. The warrant repricing resulted in an immediate and incremental increase of approximately $50,000 in the estimated fair value of the common warrants issued in the Company’s October 2022 public offering. The common warrants were valued on the date of the warrant repricing using the Black-Scholes option pricing model based on the following assumptions: March 2023 Conversion price before $ 6.30 Conversion price after $ 2.65 Term (years) 4.9 Volatility 123 % Dividend rate 0 % Risk free rate 4.20 % On November 22, 2023, the Company entered into an At The Market Offering Agreement (the "Offering Agreement”) with Wainwright with respect to an at-the-market offering program under which the Company may offer and sell, from time to time, shares of its common stock, $0.001 par value having an aggregate offering price of up to $1,288,000 through Wainwright as its sales agent. The shares of Common Stock to be offered and sold under the Offering Agreement, will be offered and sold pursuant to the Company’s shelf registration statement. For the quarter ended March 31, 2024, the Company sold a total of 221,736 shares of common stock under the Offering Agreement at an average selling price of $0.45 per share, resulting in net proceeds of approximately $99,000. Nasdaq’s listing standards provide that a company may be delisted if the bid price of its stock drops below $1.00 for a period of 30 consecutive business days. On January 8, 2024, we received written notice from the Nasdaq Listing Qualifications Department notifying the Company that it was not in compliance with the minimum bid price requirements set forth in Nasdaq Listing Rule 5550(a)(2) for continued listing on the Nasdaq Capital Market, due to the bid price of the Company’s common stock closing below the minimum $1.00 per share for the thirty (30) consecutive business days prior to the date of the Notification Letter. In accordance with listing rules, the Company was afforded 180 days, or until July 8, 2024, to regain compliance. Net Loss Per Share Net loss per share is computed by dividing the net loss by the weighted average number of common shares outstanding. For the purpose of calculating basic net loss per share, the additional shares of common stock that are issuable upon exercise of the pre-funded warrants have been included since the shares are issuable for a negligible consideration and have no vesting or other contingencies associated with them. All pre-funded warrants previously issued have been exercised and none are outstanding. The calculation of the basic and diluted earnings per share is the same for all periods presented, as the effect of the potential common stock equivalents noted below is anti-dilutive due to the Company’s net loss position for all periods presented. Anti-dilutive securities consisted of the following at March 31: 2024 2023 Common stock equivalents of convertible promissory note and accrued interest 16,906,190 2,946,525 Warrants 1,238,869 1,253,387 Stock options 6,097 6,400 Total 18,151,156 4,206,312 Warrants A summary of warrant activity for the three months ended March 31, 2024 is as follows: Number of Shares Weighted-Average Exercise Price Per Share Weighted- Average Remaining Contract Term Balance at December 31, 2023 1,238,869 $ 3.14 4.57 Warrants granted - Pre-funded warrants granted - Warrants exercised - Exercisable and Outstanding at March 31, 2024 1,238,869 $ 3.14 4.32

Commitments and Contingencies Disclosure [Text Block]	10. Commitments and Contingencies The Company, entered into a Manufacturing and Supply Amending Agreement #2 with CBR Systems, Inc. (“CBR”) with an effective date of July 13, 2020 (the “Amendment”). The Amendment modified the Manufacturing and Supply Agreement entered into on May 15, 2017 and Amendment #1 dated March 16, 2020 by the Company and CBR. The Amendment, among other things, revised the amounts of certain products to be purchased, pricing of those products and removal of the safety stock requirement. In addition, the Amendment updated the financial requirement to exclude convertible debt from the definition of short-term debt under events or conditions that constitute a default. The Amendment states that the Company’s cash balance and short-term investments net of non-convertible debt and borrowed funds that are payable within one year must be greater than $1,000,000 at any month end. The Company was in compliance with this agreement as of March 31, 2024. In the normal course of operations, the Company may have disagreements or disputes with customers, employees or vendors. Such potential disputes are seen by management as a normal part of business. As of March 31, 2024, management believes any liability that may ultimately result from the resolution of these matters will not have a material adverse effect on the Company’s consolidated financial position, operating results or cash flows.

Subsequent Events [Text Block]	11. Subsequent Events On April 19, 2024, the Company received a notice (the “Nasdaq Notice”) from Nasdaq that the Company does not presently comply with Nasdaq’s Listing Rule 5550(b)(1) that requires the Company to maintain a minimum of $2,500,000 in stockholders’ equity for continued listing. Additionally, as of the date of this report, the Company does not meet the alternatives of market value of listed securities or net income from continuing operations under Nasdaq Listing Rules. The Nasdaq Notice does not have any immediate effect on the listing of the Company’s common stock on the Nasdaq Capital Market and the Company has 45 calendar days from the date of the Nasdaq Notice to submit a plan to Nasdaq to regain compliance with Nasdaq’s continued listing rules. If the Company’s plan is accepted, Nasdaq can grant the Company an extension of up to 180 calendar days from the date of the Nasdaq Notice for the Company to evidence compliance with its plan and with the relevant Nasdaq continued listing rules. In connection with the Company’s plan, once submitted, Nasdaq staff will consider such things as the likelihood that the plan will result in compliance with Nasdaq’s continued listing criteria, the Company’s past compliance history, the reasons for the Company’s current non-compliance, other corporate events that may occur during staff’s review period, the Company’s overall financial condition, and the Company’s public disclosures. If, in the staff’s consideration of the Company’s plan, the staff were to determine that the Company would not be able to cure the deficiency, then Nasdaq would provide notice that the Company’s common stock would be subject to delisting. Upon such a notice, the Company would have the right to appeal that determination and the Company’s common stock would continue to remain listed on the Nasdaq Capital Market until the completion of the appeal process. The Company is considering various actions that it may take in response to the Nasdaq Notice in order to provide to Nasdaq the required plan to regain compliance with the continued listing requirements, but the Company has not currently completed its internal analysis regarding the items to be included in its plan to be submitted to Nasdaq staff.

Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such Securities and Exchange Commission (“SEC”) rules and regulations and accounting principles applicable for interim periods. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Events subsequent to the balance sheet date have been evaluated for inclusion in the accompanying condensed consolidated financial statements through the date of issuance. Operating results for the three months ended March 31, 2024 are not necessarily indicative of the results that may be expected for the Company’s fiscal year ending December 31, 2024. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in ThermoGenesis Holdings’ Annual Report on Form 10-K for the year ended December 31, 2023.
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The consolidated financial statements include the accounts of ThermoGenesis Holdings and its wholly-owned subsidiaries, ThermoGenesis Corp. and TotipotentRX Cell Therapy, Pvt. Ltd and ThermoGenesis Corp’s majority-owned subsidiary, CARTXpress Bio, Inc. (“CARTXpress Bio”). All significant intercompany accounts and transactions have been eliminated upon consolidation. The 20% ownership interest of CARTXpress Bio that is not owned by ThermoGenesis Holdings is accounted for as a non-controlling interest as the Company has an 80% ownership interest in CARTXpress Bio. Earnings or losses attributable to other stockholders of a consolidated affiliated company are classified separately as "non-controlling interest" in the Company's consolidated statements of operations. Net loss attributable to non-controlling interests reflects only its share of the after-tax earnings or losses of an affiliated company. The Company's condensed consolidated balance sheets reflect non-controlling interests within the equity section.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Standards In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which is intended to enhance the transparency and decision usefulness of income tax disclosures. Notably, the ASU requires entities to disclose specific categories in the effective tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold, as well as disclosures of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024 on a prospective basis. Retrospective application to each period presented in the financial statements is permitted. We are currently evaluating the impact of this standard on our consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” which requires all public entities, including those that have a single reportable segment, to provide enhanced disclosures primarily about significant segment expenses. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The new guidance is required to be applied on a retrospective basis, with all required disclosures to be made for all prior periods presented in the financial statements. The segment expense categories and amounts disclosed in prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. We are currently evaluating the impact of this standard on our consolidated financial statements. In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements—Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative.” This ASU modifies the disclosure or presentation requirements of a variety of Topics in the Codification by aligning them with the SEC’s regulations. The amendments to the various Topics should be applied prospectively, and the effective date for the Company for each amendment will be determined based on the effective date of the SEC’s removal of the related disclosure from Regulation S-X or Regulation S-K. If the SEC has not removed the applicable requirement by June 30, 2027, then the related amendment in ASU 2023-06 will be removed from the Codification and will not become effective. Early adoption of this ASU is prohibited. We are currently evaluating the new ASU to determine if it will have an impact on the disclosures or presentation in our consolidated financial statements.
